Mage? Spell Engineer!

For transformation, Rorschach needs to figure out what process the transmutation dust went through in the blue light barrier of Dryats, and then how part of it was stabilized and transformed into a blue crystal containing ether. He needs to scale up the process so that the more blue crystals are produced in the end and the less powder decays prematurely, the better.

However, this is only one of the routes. What he needs more in his vision is to directly extract the ether and obtain a continuous "magic well". If successful, it would become the centerpiece of Rorschach's own future magic tower.

"When studying the transformation process, we can easily be confused by the appearance and pay too much attention to what has changed. People's true understanding of the essence of the process often starts from the unchanged elements." Today is also the day when Luo Xia is taking a class at the Normal University. Now he I can already slightly remember the names of the students in the audience.

Today's class was held in the laboratory, and Rorschach had to patrol around to correct the students' incorrect operations: "Andrew, you shouldn't hold the weights with your hands."

"Sorry sir, but I'm Andre."

"Uh, okay Andre, I will remember it from now on, and you should also remember the operating procedures of the experiment."

The students removed the white phosphorus from the cold water, dried it, and placed it in an Erlenmeyer flask lined with fine sand. A glass tube is inserted into the cork, and a small air bag is tied to the part of the glass tube exposed outside the bottle.

It is not easy to assemble this simple device for a class. For example, there are no artificial rubbers and artificial polymers in this world, and the airbags are made of sheep intestines and gum tree latex.

The experiment Rorschach wanted to take them to do was extremely basic, which was the burning of white phosphorus in a closed system. Students only need to weigh the system before and after igniting the white phosphorus and will find that the total weight of the system has not changed. The mass of reactants and products is equal, and mass is the property that does not change during the combustion process.

The experiment is very simple, but the ignition process has certain dangers. It is very important for these students to gradually learn to conduct experiments in a standardized manner. The ignition point of white phosphorus is very low. After Rorschach demonstrated, heating the mouth of the glass tube and inserting the stopper and the glass tube into the flask can ignite the white phosphorus, emitting white smoke, light and heat.

If nothing else, there was an accident: the paper used to absorb water for white phosphorus is very rough. A wise man was afraid that the residual water on the white phosphorus would prevent it from being ignited, so a person rubbed it hard in the corner of the classroom and successfully used the rough paper. Rub the fire and let the white phosphorus burn happily in the air.

"Ah!" The white phosphorus taken was only the size of a bean, and it turned into a puff of white smoke and disappeared. However, the absorbent paper was ignited by the heat released by the sample, and the white phosphorus work continued on the iron-covered experimental bench.

Rorschach did not use magic to extinguish the flames immediately. He just used magic to disperse the toxic smoke, and then observed how the classmates who caused the accident put out the fire.

Now the panicked guy has a bucket of sand at his feet and a bottle of water on the table.

Water. Water. The student nervously grabbed the water and was about to pour it down. Then he found that his hand was being held tightly.

I went and held him down with the hand of the mage. He still wanted to resist Rorschach but was almost made to cry by his own student. Battis watched longingly as the teacher walked over with a black face. A ray covered in frost erupted from his hand, hitting the paper accurately and extinguishing the flame.

"Batis?"

"You were right this time, sir." The students who were watching laughed out loud.

This guy is a bit stupid. Rorschach began to torture: "Batis, why are you grabbing the bottle in your hand?"

"Because I want to put out a fire, sir, and there's water in the bottle."

"Can you tell me why there is water in the bottle?"

"Because. Oh, because there is white phosphorus. White phosphorus is stored in pure water, sir." You finally know, Master Battis.

Rorschach let go of Battis, who had failed in his attempt to "send phosphorus in the fire": "I said at the beginning of the experiment that accidental fires during this experiment can be put out by pouring sand up."

In fact, Battis pouring the cup may not ignite the phosphorus before extinguishing the flame, but this is undoubtedly an action that increases the risk. Immediately pouring the colorless and transparent liquid when encountering a fire is something that needs to be reversed in laboratories and workshops. As a habitual operation, Rorschach was thinking about the day when he should get active alkali metals to open the eyes of these people.

He looked around and said to the students who were watching: "If you continue without finishing the experiment, after recording the experiment report, you must attach a question after the report: Why can this experiment reflect the 'conservation of matter' in the process of non-magical changes?" thoughts, and.”

If you are an apprentice of the Tower of Stars, you should continue to think about what magic will break this conservation law, what is its manifestation and the mechanism of the spell.

But they are ordinary people. According to the agreement between the school and the magic guild, he changed the topic: "And based on the 'three elements of combustion' we learned before, think about and design three safe fire extinguishing and fire prevention plans."

Rorschach felt that this assignment was well done, but he could tell by looking at the students' expressions that it was not. Rorschach believed that the reason for the good assignment was that "designing effective fire-fighting measures based on the conditions and laws of combustion" is a new trend in the world that has just bid farewell to handicraft production. This is a very lacking link in the industry. If these students can work in workshops in the future, this technology alone will be of great value.

It’s definitely not a secret pleasure for these students to find something to do after class. Rorschach said to Battis with a serious face: "This classmate, you need to write five items and a series of reflections on wrong operations."

As soon as these words came out, other students suddenly felt that their homework was relatively less. Battis's face dropped, and the corners of other people's mouths couldn't help but curl up - pain and happiness were achieved in this classroom. Conservation.

"Others should also reflect on and summarize the shortcomings of the experiment. For example, Andre can review the operating specifications of the scale." The teacher's "magic" broke the conservation law of "pain-pleasure". Now everyone is in pain, but the difference is only in degree. .

Rorschach did not feel satisfied just because he "tortured" the students. He assigned these assignments so that the students could do better and safer experiments in the future.

It would be great if some of you could move forward in exploring the truth or benefit more people even if you don't know magic. "Cultivation of the best teachers for the advancement of human wisdom and art", the slogan was shouted loudly. Luo Xia looked at the clumsy students in the classroom and sighed secretly in his heart.

In the next class, he planned to put together another device based on the device used to prove the "thermal work equivalent" in "Examining Thermodynamic Conversion and the Efficiency Limit of Heat Engines", so as to explain "energy conservation under non-magical systems" to these students.

As for the system that includes magic, Rorschach actually thinks he can explain it properly. From the airship to the current workshop where the alchemy department is technically involved, the content of magic itself has gradually penetrated into industrial production. Even if only mages and apprentices monopolize these positions, the supply exceeds demand. .

The workshop is full of noise, danger, waste water and gas. How many noble mages and apprentices who are often well-paid are willing to stay? If the device invented by Rorschach can solve the supply of ether, then people without magic can be trained as operators of magic circles in factories, and even participate in the design of magic circles and spells, even though they themselves do not have enough magic power.

What's that? A mage who can't cast his own spells?

Rorschach looked at the students packing up the experimental equipment and laughed at his own random thoughts.

The bell rang, and the students rushed to the next classroom. After checking the arrangement of the equipment, Rorschach was about to leave, but was stopped by a colleague at the door: "Teacher Rorschach, stay!"

"You have something to do with me?"

"I am the instructor. Teacher Drouot. I have many things to tell you. Because you always run away after class and never come to the teaching and research room, so I can only come here to fight an ambush." ​​To inform Rorschach. The teacher is a young man, about thirty years old, with a faint smell of tobacco.

"Then you won the battle, please tell me."
